Patients with moderate to severe COVID-19 disease develop hypoxemic respiratory failure demonstrating profound degrees of hypoxia with little or no distress. This has put the conventional management consisting of an early intubation in question. In this case series, we attempted an integrated oxygen strategy utilizing non invasive ventilation with standard oxygen therapy (SO) via nasal cannula. We managed both the patients with successful outcomes, without the need of intubation. Hence, integrated oxygen therapy was successfully utilized for the ventilatory management of moderate to severe COVID-19 patients by improving oxygenation, making patients more comfortable and reducing the work of breathing. By complete avoidance of intubation, this technique might help in preservation of much-needed critical care ventilators and help improve patient outcomes in the areas hit hard by the pandemic.

IntroductionNon-invasive ventilation (NIV) is recommended as first-line therapy in respiratory failure of critically ill immunocompromised patients as it can decrease intubation and mortality rates as compared with standard oxygen. However, its recommendation is only conditional. Indeed, the use of NIV in this setting has been challenged recently based on results of trials finding similar outcomes with or without NIV or even deleterious effects of NIV. To date, NIV has been compared with standard oxygen but not to high-flow nasal oxygen therapy (HFOT) in immunocompromised patients. Several studies have found lower mortality rates using HFOT alone than when using HFOT with NIV sessions in patients with de novo respiratory failure, and even in immunocompromised patients. We are hypothesising that HFOT alone is more effective than HFOT with NIV sessions and reduces mortality of immunocompromised patients with acute hypoxemic respiratory failure.Methods and analysisThis study is an investigator-initiated, multicentre randomised controlled trial comparing HFOT alone or with NIV in immunocompromised patients admitted to intensive care unit (ICU) for severe acute hypoxemic respiratory failure. Around 280 patients will be randomised with a 1:1 ratio in two groups. The primary outcome is the mortality rate at day 28 after inclusion. Secondary outcomes include the rate of intubation in each group, length of ICU and hospital stay and mortality up to day 180.Ethics and disseminationThe study has been approved by the ethics committee and patients will be included after informed consent. The results will be submitted for publication in peer-reviewed journals.Trial registration numberNCT02978300

IntroductionA palliative approach to intensive care unit (ICU) patients with acute respiratory failure and a do-not-intubate order corresponds to a poorly evaluated target for non-invasive oxygenation treatments. Survival alone should not be the only target; it also matters to avoid discomfort and to restore the patient’s quality of life. We aim to conduct a prospective multicentre observational study to analyse clinical practices and their impact on outcomes of palliative high-flow nasal oxygen therapy (HFOT) and non-invasive ventilation (NIV) in ICU patients with do-not-intubate orders.Methods and analysisThis is an investigator-initiated, multicentre prospective observational cohort study comparing the three following strategies of oxygenation: HFOT alone, NIV alternating with HFOT and NIV alternating with standard oxygen in patients admitted in the ICU for acute respiratory failure with a do-not-intubate order. The primary outcome is the hospital survival within 14 days after ICU admission in patients weaned from NIV and HFOT. The sample size was estimated at a minimum of 330 patients divided into three groups according to the oxygenation strategy applied. The analysis takes into account confounding factors by modelling a propensity score.Ethics and disseminationThe study has been approved by the ethics committee and patients will be included after informed consent. The results will be submitted for publication in peer-reviewed journals.Trial registration numberNCT03673631

Introduction: Oxygen therapy remains the cornerstone for managing patients with severe SARS-CoV-2 infection and several modalities of non-invasive ventilation are used worldwide. High-flow oxygen via nasal canula is one therapeutic option which may in certain cases prevent the need of mechanical ventilation. The aim of this review is to summarize the current evidence on the use of high-flow nasal oxygen in patients with severe SARS-CoV-2 infection.Material and Methods: We conducted a systematic literature search of the databases PubMed and Cochrane Library until April 2021 using the following search terms: “high flow oxygen and COVID-19” and “high flow nasal and COVID-19’’.Results: Twenty-three articles were included in this review, in four of which prone positioning was used as an adjunctive measure. Most of the articles were cohort studies or case series. High-flow nasal oxygen therapy was associated with a reduced need for invasive ventilation compared to conventional oxygen therapy and led to an improvement in secondary clinical outcomes such as length of stay. The efficacy of high-flow nasal oxygen therapy was comparable to that of other non-invasive ventilation options, but its tolerability is likely higher. Failure of this modality was associated with increased mortality.Conclusion: High flow nasal oxygen is an established option for respiratory support in COVID-19 patients. Further investigation is required to quantify its efficacy and utility in preventing the requirement of invasive ventilation.

The objective: to evaluate the effect of high-flow oxygen and non-invasive ventilation on the mortality rate in adults with severe respiratory failure caused by the new coronavirus infection in the intensive care unit (ICU).Subjects and methods. A one-center retrospective study was conducted. Electronic medical files of patients treated in the ICU from April 1 to May 25, 2020, were analyzed. Totally, 101 medical files were selected, further, they were divided into two groups. Group 1 (n = 49) included patients who received oxygen insufflation, and should it fail, they received traditional artificial ventilation. No non-invasive respiratory therapy was used in this group. Group 2 (n = 52) included patients who received high-flow oxygen therapy and non-invasive ventilation. The mortality rate in the groups made a primary endpoint for assessing the impact of high-flow oxygen therapy and non-invasive ventilation. The following parameters were also analyzed: drug therapy, the number of patients in whom non-invasive techniques were used taking into account the frequency of cases when these techniques failed, and the number of patients in whom artificial ventilation was initiated.Results. In Group 2, non-invasive methods of respiratory therapy were used in 31 (60%) cases. High-flow oxygen therapy was used in 19 (36%) of them; in 13 cases this method allowed weaning them from the high flow. Non-invasive ventilation was used in 18 cases, in 12 patients it was used due to progressing severe respiratory failure during humidified oxygen insufflation, in 6 patients – after the failed high-flow oxygen therapy. In Group 1, 25 (51%) patients were intubated and transferred to artificial ventilation, in Group 2, 10 (19.2%) underwent the same. The lethal outcome was registered in 23 (47%) cases in Group 1, and in 10 (19.2%) in Group 2 (p = 0.004). Analysis of drug therapy in the groups revealed the difference in the prescription of pathogenetic therapy. Logistic regression demonstrated the effectiveness of the combination of tocilizumab + a glucocorticoid in reducing the frequency of lethal cases (p = 0.001).Conclusion. The use of non-invasive respiratory support in adults with severe respiratory failure caused by the new coronavirus infection combined with therapy by tocilizumab + a glucocorticoid can reduce the incidence of lethal cases.
